3. General Information
3.1. DESCRIPTION
INOXPA’s KVB-25 progressive cavity pump forms part of our range of positive-displacement pumps with helical rotor, intended
for viscous fluids. This pump is specially designed for emptying closed barrels with the connection diameter of 60mm or wider.
The hydraulic parts that form the pump are the rotor and the stator. The rotor is a round-section worm. The stator has two ribs
and its pitch doubles that of the rotor, thus allowing empty cavities between the stator and the rotor. These cavities are used
to transport the fluid. When the rotor turns within the stator, the cavities move longitudinally from the suction area to the
discharge nozzle.
This kind of pumps is suitable for pressures from 6 bar.
All pump parts in contract with the pumped product are manufactured in AISI 316L stainless steel. The stator is manufactured
in NBR, according to the FDA norm, and the standard sealing is EN 12756 mechanical seal.
This equipment is suitable for his use in food process.

4.2. TRANSPORT AND STORAGE
Lift the pump through the drive support as is shown below:

8 4.Installation 2021/11
4.3. LOCATION
Position the pump into the barrel, always having the stator submerged.
Make sure that the pump does not work in dry because the stator will be deteriorated quickly.
4.4. ELECTRICAL INSTALLATION
Leave the connecting of the electrical motors to qualified personnel. Take the necessary measures to
prevent any breakdowns in the connections and wires.
The electrical equipment, the terminals and the components of the control systems may still carry an
electric charge even when disconnected. Contact with them may put the safety of operators at risk,
or cause irreparable damage to the material.
Before manoeuvring the pump, make sure that the electric box is switched off.
•Connect the motor in accordance with the instructions supplied by the manufacturer of the same.
•Check the direction of the rotation (see the signaling label on the pump).
Put the pump motor into operation momentarily. Make sure, by looking at the pump from
above, that the motor’s ventilator is rotating in a clockwise direction.
Check ALWAYS the direction of the motor’s rotation with liquid inside the pump.

2021/11 5.Start-up 9
5. Start-up
Before putting the pump into operation read carefully the instructions on installation given in
Chapter 4. Installation .
5.1. START-UP
Read Chapter 8. Technical Specifications carefully. INOXPA will not assume responsibility for any
improper or incorrect use of the equipment.
Do not touch the pump or the piping while it is pumping products at a high temperature.
5.1.1. Checks to be carried out before putting the pump into operation
•Fully open the cut-off valve on the discharge pipe.
•Check that the stator is submerged.
The pump must NEVER rotate without liquid.
•Check that the rotation direction of the motor is correct.
•Check that the power supply matches the rating indicated on the motor plate.
5.1.2. Checks to be carried out on putting the pump into operation
•Check to make sure that the pump is not making any strange noises.
•Check to see if the absolute inlet pressure is sufficient, in order to avoid cavitations in the pump. Consult the curve for the
minimum required pressure above the steam pressure (NPSHr).
•Monitor the delivery pressure.
•Check that there are no leaks in the sealed areas.
Monitor motor consumption in order to avoid a circuit overload.

Leak in mechanical seal.
5, 6, 8.
Probable causes
Solutions
1
Wrong rotation direction.
Change the direction of the rotation.
2
Delivery pressure is too high.
If necessary, decrease the load losses by increasing the diameter
of the piping, for example.
3
The viscosity of the liquid is too high.
Decrease the viscosity by heating the liquid, for example.
4
The temperature of the liquid is too high.
Decrease the temperature of the liquid by cooling it.
5
Mechanical seal either damaged or worn.
Replace the seal.
6
Unsuitable stator or O-ring for the liquid in question.
Fit more suitable O-ring by consulting the supplier with respect to
the same.
7
There are foreign bodies in the liquid.
Place a filter at the suction piping.
8
The tension of the mechanical seal spring is too low.
Adjust in accordance with the instructions given herein.
9
The pump speed is too low.
Increase the speed.
10
The stator is worn out.
Replace the stator.
11
Very abrasive liquid.
Mount the more suitable material of stator (check with the
supplier).
If the problems persist stop using the pump immediately. Contact the pump manufacturer or his
representative.

7. Maintenance
7.1. GENERAL MAINTENANCE
This pump, as with any other machine, needs to be maintained. The instructions contained in this manual deal with the
identification and replacement of the spare parts. These instructions have been drawn up by maintenance staff and are
destined for those people who are responsible for supplying spare parts.
Read carefully Chapter 8. Technical specifications .
All the parts or materials that are changed must be duly eliminated/recycled in accordance with the
prevailing directives in each area.
ALWAYS disconnect the pump before starting out on any maintenance work.
7.1.1. Check the mechanical seal
Periodically check that there are no leaks in the shaft area. Should there be any leaks in the mechanical seal area, replace the
same pursuant to the instructions given in the section entitled Stripping and Assembly of the pump.
7.2. STORAGE
Before being stored the pump must be completely emptied of liquids. Avoid, as far as possible, the exposure of the parts to
excessively damp atmospheres.
7.3. CLEANING
The use of aggressive cleaning products such as caustic soda and nitric acid may give rise to skin
burns.
Use rubber gloves during the cleaning process.
Always use protective goggles.
To clean the pump manually, disassemble the pump as indicated in the Pump disassembly/assembly instructions.
In order to remove any remains of cleaning products, ALWAYS rinse the element in question with clean water after completing
the cleaning process.
